What a New Build Loft Conversion is and how it works?

When building a home, the roof space is often ignored or left incomplete for later. That’s why a new-build loft conversion is opted for. It is a process of transforming the unused roof space into a properly designed attic space.

These conversions often require extra structural work to create safe head height and support, but they bring valuable living space without any hassle to move things around. 

Benefits of a Loft Conversion in New Build Properties

Loft conversion brings lots of initial design challenges, but it also brings many incredible benefits: 

Get Extra Space into Your Home 

Building a loft can add so much extra space to your home’s existing space. Either you built a new bedroom, office, playroom, or ensuite without altering the footprint of your home. 

Add more value to your space

A well-constructed and built loft adds so much value to the existing space. It almost adds 20% more resale value. As you know, buyers love the extra space, and it makes your home stand out in a competitive market.

Eco-friendly Solutions

During the build-in procedures, more eco-friendly options can be considered, like solar plates, or any additional insulation can be installed, which can reduce heat loss and lower energy bills.

Faster Build Time 

Loft build-ins take less time and can be completed in a matter of weeks, especially when handled by specialists like ParamountBuilt, causing far less disruption.

Let’s explore the ideas for New Build Loft Conversions

The Conventional Bedroom Option

This is the most common idea for converting the new build loft into a bedroom. With time, whenever there is a need to extend the family or plan to build a guest room, the loft space can be transformed.

Home Office or Creative Studio 

You can make your loft space into a fully functional office or a cosy studio space for art, photography, or anything else. 

Walk-in Wardrobe 

The loft space can be utilised as a walk-in wardrobe. This turns unused roof space into a luxury dressing area with fitted wardrobes, mirrors, spotlights, and seating. 

Nursery or Future-Proof Bedroom 

This idea is perfect for growing families, as it creates a peaceful nursery that can adapt into a bedroom as children get older.

Other ideas include a gym, a cinema or an Airbnb space. 

Factors to Consider Before Converting a Loft in a New Build

The following factors must be considered before converting a loft into a new build:

• The Roof  Type and Structure: Most new-build houses are built with trussed roofs, which might need extra structural and/or material support like steel or concrete. 

• Head Height: There is a special head height, which is 2.2 m at the highest point. If it is low, a dormer or roof redesign may be required. 

• Planning Permission: Of course, there should be planning permission for loft constructions, as new builds sometimes have restrictions that need to be approved with planning permission. 
• Developer Restrictions: The new build loft conversion sometimes demands tricky designs that limit external changes. Always check with the developer or management company. 

• Budget and Complexity: New-build lofts often cost more due to truss reinforcement or roof adjustment. Therefore, budgeting beforehand should be a priority. 

How Much Does a New Build Loft Conversion Cost?

The new build loft conversion averages between £55,000 and £120,000. This cost can vary widely depending on the complexity of the conversion. There is a different cost for the trussed roof conversion and smaller and larger areas.

It also depends on the type of design and material used for constructing a loft. Like Velux, dormer, and hip-to-gable, all of them have different rates.

Can You Do a Loft Conversion on a New Build?

Absolutely yes, you can transform a loft into a new build space, even if you think it’s a modern trussed roof. Most of the newly built houses are not designed with traditional attic spaces, so builders might install steel beams or reinforce the existing trusses to make the conversion safe and compliant with building regulations. 

On the contrary, many of the homes that are built can’t be converted, but that’s not true. With the right structural design and correct planning permission from the developer or local authority, a new-build loft conversion can add a full extra room. Add more value to the property and make smart use of wasted roof space.
